6.2 Programming Timing Recipes (Continued)
Refill Time: Sets the time required for the material to flow into the orifice after each
drop has been ejected. Time is set in msec with 0.1 msec resolution.
Reserved 2 to Reserved 5: These timers are not used for the HV-2000. They are set to
zero by default.
Dwell Time: Sets the time required for the material to be ejected from the orifice. Time
is set in msec with 0.1 msec resolution.
Adjust Refill Time for First Drop: There are two time values for adjusting the size and
quality of the first drop. The programming is discussed here; a more detailed
explanation is in Appendix 1: First Drop Compensation.
 Add xxx msec: is a time value that is added to Refill Time. Referring back to
Figure 6-1, 2.0 msec (original Refill Time) + additional 0.5 msec = 2.5 msec
Total Refill Time. In DROP mode, this value is added to every drop (described
in Section 6.3). However, in LINE mode this value is added only to the very
first drop (described in Section 6.4).
 Add XX msec after YY seconds: is a time value added to the Refill Time
after the jet is idled for a defined number of seconds. This additional time is
added only to the first drop in both Drop and Line Mode. Referring again to
Figure 6-1, the Refill Time for the first drop after 20 seconds at idle would be
2 msec (original Refill Time) + additional 0.8 msec = 2.8 msec Total Refill
Time. This applies to only the first drop.
Note: Once the names and timing values have been chosen for a recipe, be sure to

Note: this is the value of Refill+ displayed on the LCD screen of
the HV-2000C Controller (see Section 3.5).
Note: this is the value of Refill++ displayed on the LCD screen of
the HV-2000C Controller (see Section 3.6). In general, the value of
Refill++ is slightly larger than Refill +.
